Following are the drawbacks or disadvantages of PIR sensor: They have lower sensitivity and less coverage compare to microwave sensors. It does not operate greater than 35 degree C. It works effectively in LOS (Line of Sight) and will have problems in the corner regions. It is insensitive to very slow motion of the objects.
Jan 28, 2014· PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR sensor and circuitry is fixed and costs a few dollars. The lens costs only a few cents and can change the breadth, range, sensing pattern, very easily.

Jan 25, 2020· Jan 25, 2020· The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can ''see'' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount ...
The first three lines of the Code starts with declaration of variables from hardware such as the LED uses pin 13 and the PIR Sensor uses pin 9. The value uses pin 0 because it is the receive pin. Next, is the usual void setup which indicates the first part of the Code, that describes the LED as OUTPUT (off). It also means the PIR Sensor is ...
